Figure 2.

Graphical description of the VL effects on brain–behavioral relationship in pain. The targeted cortical brain areas are colored as follows: primary motor (M1; beige), primary somatosensory (S1; pink), secondary somatosensory (S2; pale blue), medial frontal (purple), dorsolateral (green), and parietal (yellow). For each cortical area, the pain tested behavior, the expected neurophysiological effect, ie, suppression or facilitatory, and the direction of the behavioral effects are presented. References are presented in brackets. VL, virtual lesion.
